What If My Patient Just Isn’t Getting Any Better? Is the patient shaking the suspension?
Did you pulse dose?
Did the pharmacist dispense generic pred?
Did the pharmacist dispense (illegally) generic FML?
Does the patient have steroid-induceduveitis?
Steroid-Induced Uveitis
First observed in steroid provocative studies in glaucoma
Incidence is higher in African-Americans (5%) than in caucasians (0.5%)
Symptoms include pain, photophobia, ciliaryflush, anterior chamber cells and/or flare
Treat by discontinuing or reducing steroid and substituting NSAID

STEROID-INDUCED OCULAR HYPERTENSION
Interesting Facts
Occurs in both healthy and glaucomatous eyes
Develops in 2-8 weeks
More prevalent with topical ketone-based steroids
Dissipates within one week after steroids are discontinued
Incidence of IOP Response
One-third of general population are “steroid responders” (≥ 3 mm Hg)
7-8% are “high” responders (≥ 10 mm Hg)
Patients Predisposed to IOP Response
Patients with POAG
Close relatives of patients with POAG
Children under 10 years of age

What To Do About It
Discontinue steroid or reduce dosing frequency
Reduce steroid concentration (↑ cost)
Change to FML or Lotemax (↑ cost)
Treat with topical ocular hypotensive agents
Avoid

Two mechanisms cause gel to immediately thin in the eye
Interesting Facts About The Gel
No shaking required except for initial “flick” to get it into dropper tip
Essentially no blurred vision in clinical trials
pH 6.5 vs 5.5 for suspension
Specified in grams, not milliliters
5g in 10 ml bottle

STEROIDS AND CATARACT FORMATION
5/15/2013
10
Appearance of Steroid-Induced Cataract
• Posterior subcapsular
• Cannot be differentiated from early complicated cataract, radiation cataract or age-related posterior subcapsular cataract
Mechanism of Steroid-Induced Cataract Formation Formation of Schiff base intermediates
between the steroid C-20 ketone group and nucleophilic groups such as ε-amino groups of lysine residues of lens proteins
More Frequent with NonocularSteroids Oral
Inhaled
NOT intranasal
Interesting Facts About Steroid-Induced Cataracts Usual time to onset is 1 year with 10 mg/day of
prednisone (but can occur in a little as 2 months on 5 mg/day)
Incidence of oral steroid cataract is 6% to 39% Strong association between inhaled steroids and
PSC cataract No clear association between intranasal steroids and
PSC cataract Loteprednol (Lotemax) does not cause cataracts Individual susceptibility (Hispanics)
THERAPEUTIC INDICATIONS FOR
STEROIDS
Fundamental Steroid Guidelines
Choose steroid For short-term or IOP no concern
Pred Forte, Durezol, or Lotemax For long-term or IOP a concern
LE 0.5%, LE 0.2%, FML, or Vexol Pulse-dose Monitor IOP in first 2-6 weeks NO REFILLS! Use shortest effective course of therapy Avoid in presence of epithelial HSV, mycobacterial,
and fungal infection

Infiltrative Keratitis/CLARE
CLARE
Initially thought to be primarily due to hypoxia
An inflammatory response to toxins produced by less virulent strains of gram negative bacteria
Recurrent episodes common
CLARE is NOT a marker for microbial keratitis
Sweeney, et al. Eye Contact Lens 2007
Differential Diagnosis of Corneal Ulcers vs. Sterile Infiltrates
Ulcer (MK) Rare
Usually painful
Tend to be central
1 to 1 staining defect to lesion ratio
Cells in anterior chamber
Generalized conjunctivalinjection
Usually solitary lesion
Possible tear lake debris
Eyelid swollen
Infiltrate
Common
Mild pain
Tend to be peripheral
Staining defect size relatively small
No cells in anterior chamber
Sector skewed injection pattern
Can be multiple lesions
Clear tear lake
Eyelid not swollen
Infiltrate
Common
Mild pain
Tend to be peripheral
Staining defect size relatively small

Management of CLARE
Topical steroid alone If cornea is clear/no epithelial
compromise Combination antibiotic/steroid
Pulse-dose q2h for 1-2 days, then q.i.d. for 4-5 days
Address CL hygiene and wearing time: Daily wear only!Otherwise, CLARE is likely to recur
Preferred Antibiotic-Steroid Combos
Steroids in Microbial Keratitis
Steroids for Corneal Ulcers Trial (SCUT)
Srinivasan M, et al. Arch Ophthalmol 2012;130(2):143-150.
SCUT Conclusions
“Conclusions: We found no overall difference in 3-month BSCVA and no safety concerns with adjunctive corticosteroid therapy for bacterial corneal ulcers.”
“Application to Clinical Practice: Adjunctive topical corticosteroid use does not improve 3-month vision in patients with bacterial corneal ulcers.”*
*Exceptions: Patients with “finger counting” VA or worse at baseline, and patients with completely central ulcers.

Management of GPC
Discontinue contact lens wear if possible
If not, use daily disposables

Educate patient on CL hygiene, wearing schedule, etc.
Lotemax for Treatment of Dry Eye Inflammation Lotemax was compared with placebo for
treatment of the inflammatory component of dry eye
Randomized, double-masked, placebo-controlled, multicenter comparison
Patients with dry eye (n=66) 32 patients treated with Lotemax 34 patients treated with placebo
Subjects received either Lotemax or placebo QID in both eyes for 4 weeks
Pflugfelder SC, Maskin SL, Anderson B, et al. Am J Ophthalmol 2004; 138: 444-57.
Lotemax for Treatment of Dry Eye Inflammation When used as monotherapy, Lotemax resulted in
greater improvement in objective signs and symptoms of dry eye than placebo at both 2 and 4 weeks
Lotemax demonstrated no clinically significant IOP elevation following 1 month of therapy
Pretreatment with Lotemax prior to cyclosporine treatment showed: 75% lower stinging rate 68% lower rate of discontinuation with
cyclosporine therapySheppard JD, et al. Topical loteprednol pretreatment reduces cyclosporine
stinging in chronic dry eye disease. J Ocul Pharmacol Ther. 2011;27:23-7

Why Do Antihistamines Cause Dry Eye?
5/15/2013
16
Parasympathetic (Cholinergic) Innervation of Lacrimal Gland
Antihistamines
• H1 blockers reduce both aqueous and mucinproduction
• As little as 4 mg daily of chlorpheniramine maleate can produce positive Schirmer test
• Four days of once-daily loratadine (Claritin) can induce dry eye and corneal staining
• Can aggravate underlying condition of dry eye

Minimal or no signs
Palliative measures; Possibly antihistamine/ mast cell stabilizer
Level 2 Primary reason for visit is itching/other symptoms; Lifestyle is affected
Minimal or no signs
Topical steroid q.i.d. for 2 weeks, then b.i.d. for 1-2 months, then switch to anantihistamine/mast cell stabilizer if symptoms persist
Level 3 Primary reason for visit is itching/other symptoms; Lifestyle is greatly affected
Red eyes; conjunctival congestion or chemosis

Steroids in SAC Management No longer considered a last resort Limit therapy to ester-based steroids (loteprednol) Use when there are significant signs or more severe
symptoms In severe cases, dosing can be increased to q2 h for the
first 2-3 days (while awake) Schedule follow-up at 3-4 weeks to check IOP and
therapeutic response No adverse effects reported with up to 4,000 doses of
Alrex over 36 months* IOP spikes can rarely occur

ears, behind knees When treating with topical steroid, schedule a F/U exam
within 4 weeks Confirm compliance, efficacy, symptom relief Evaluate IOP and educate about long-term
management Steroids in CL wearers:
Use b.i.d. (before and after lens wear) OR Limit duration of wear and add 3rd dose before
